Expansion isn't happening with time, Time is happening due to Expansion -True or False?

It is widely realised nowadays that the Age of the Universe as a radius translates to our space (as the circumference of a circle) to match the Hubble Constant. That is each second increase in radius (light second) increases space by a close approximation to the measured Hubble Constant. I have always thought of increases in time as causing space expansion but what if it is the other way around; space expansion causes time.
If this were the case, we no longer look for a cause of time (which seems difficult) but for a cause of space expansion (which seems easier). For example, Black Holes may cause white Holes, etc.

What do you think/suggest?
